WRAPPING-MACHINE.

Specification of Letters Patent. Patented Jan, 3, 1911, Applicationfiled July a, 1908. Serial No. 442,189.

To all whom it may concern.

Be it known that I, ELMER C. Non'rmmr, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Wrapping-Machine, of whichthe following is a specification.

This invention relates to wrapping machines, and While it is adapted forwrapping various articles or packages, it is particularly designed forwrapping fruit, such as oranges, lemons, 8a:

In wrapping fruit and especially oranges it is very desirable that thefruit be handled in as expeditious a manner as possible and at the sametime that it be subjected to careful handling to prevent injury eitherby abrading the skin or bruising the fruit.

In doing the work by machinery it is necessary that the fruit bedelivered to the machine one at a time and that it be delivered at sucha time and place as to be properly positioned upon the paper which isadapted to be wrapped around it and closed by pressing the edgestogether as compactly as possible so as to prevent the accidentalloosening and possible loss of the wrapper in subsequenthandling of thefruit.

The accompanying drawings illustrate the invention and form a part ofthe specification.

"' Figure 1 is a vertical longitudinal sectional view of one form ofmachine embodying the invention. Fig. 2 is a transverse verticalsectional view showing a roll of paper and the mechanism for severing itinto proper lengths to form the wrappers. Figs. 3 and 4 are detail viewsrelating thereto. Fig. 5 is a broken top plan view, partly in section,of the wrapping mechanism. Fig. 6 is a vertical transverse sectionalView of said mechanism showing the position the parts occupy at thebeginning of the wrappmg process. Fig. 7 is a similar view showing theprocess partly completed. Fig. 8 shows the position of the parts whenthe process has been completed. Fig. 9 is a vertical transversesectional view showing the means of feeding the fruit to the machine.Fig. 10 is a plan view of the delivery end of the feeder. Fig. 11 is abroken perspective of part of the carrier. Fig. 12 is an enlargedsectional view of the pa er cutting mechanism. Fig. 13 is a broken p anview of the plunger mechanism. Fig. 14 is a face view of one of thecams.

Referring more particularly to the drawings which are for illustrativepurposes only and, therefore, are not drawn to any particular scale, 1indicates the base or main frame of the machine upon which the papermechanism is mounted at or near one end and the wrapping mechanism at ornear the other with the conveyer and fruit supply located intermediatethe ends.

J ournaled transversely of the frame 1 are two shafts 2 and 3 upon whichare mounted two sprocket wheels 4 and 5, respectively. A sprocket chain(5 is mounted u on these wheels substantially centrally of t e framewhich is provided with a series of cup-like holders 7. The sprocketwheels and chain may be driven in any suitable manner, as by means ofthe ear wheels 8 and 9 and a belt wheel 10. The chain may be of anysuitable construction and is formed or provided at suitable distancesapart with plate like links 11 upon each of which is located a suitableboss or projection 12. The boss is preferably hollow and a rod or stem13 projects therethrough and through the plate 11 and has its inner endprovided with a head 14 which is adapted to engage with the plate 11 andprevent the rod from being isconnected from the plate. Each rod carriesone of the cup-like receptacles 7 at its outer end and is held in itsextended or projected position with the head 14 in engagement with theplate 11 by means of a coiled spring 15 which is preferably madetapering with its lower end secured to the plate 11 in any suitablemanner and its outer end engagin with the bottom of the receptacle 7.

The shafts 2 and 3 are journaled near the ends of the frame 1 and aplate 16 is suported in any suitable manner, preferably y meansof abracket 17, intermediate the sprocket wheels 4 and 5 with its 11 perface substantially in alinement with t e upper portion of the wheels soas to receive and support the chain 6, and especially the links 11, soas to hold the cups 7 upright when they are receiving and carryinforward the oranges. The oranges are fed to these receptacles in anysuitable manner but I prefer to provide an inclined trough 18 which hasits inner end located adjacent to the center of the machine, or thepathtravcled by the receptacles 7, witlra discharge gate 19 which ispreferably arranged at an angle to said trough as shown in Fig. 10. Twoof the sides of the gate 20 and 21 are preferably made adjustablelaterally toward and from each other so as to properly position thedifferent sized oranges relatively to the receptacles 7 of the carrler.The bottom of the spout 18 is preferably slightly cupped as shown at 22to properly position the oranges 23 so as to be engaged by upwardlyextending fingers 24 that are secured to or form a part of a series ofrim like projections 25 mounted upon achain 26. The chain 26 is mountedupon'sprocket wheels 27 on shafts 28 which are mounted in brackets 29and 30. The Wheels 27 are mounted upon the shafts-so as to be directlyabove or in the same plane with the chain 6 and at such a distance abovethe path of the receptacles 7 that when the fingers are passed throughthe lower end of the spout 18 and the ate 19 the oranges are carriedfrom the lower end of the chute or spout 18 into a the gate 19 fromwhence they drop down through the rings 25 into the receptacle. The rearwall of the spout and the front wall of the gate are recessed as shownat 31 and 32, respectively, through which the fingersare adapted topass. The rings are so positioned upon the chain 26 that one of themwill pass under the gate every time that a receptacle 7 on the carrier 6is directly beneath, thereby providing each receptacle with an orange.To prevent the oranges from being shaken off the receptacle by the rapidmovements of the machine the chain 26 is extended a suitable distancelengthwise of the carrier 6 so as to cause the rings 25 to move forwardsimultaneously with the receptacles 7 and the rear end of the chain isslightly raised or inclined upward so that as the rings 25 are carriedforward they are also gradually lifted upward until they pass up aroundthe wheel 27 and the orange goes forward to thewrapping mechanism.

The wrapping machine is adapted to use paper which is preferablyprovided in the form of a roll 33 which is mounted on stand ards 34 atthe forward end of the machine and one end of the paper is passed downbetween rolls 35 and 36 which feed it forward to the cutting mechanismat the desired rate of speed. If desired suitable printing mechanism maybe provided which is shown in the form of a roller 37 that is suppliedwith ink from a receptacle 38 by means of rollers 39.

' The cutting mechanism for severing the str1p of paper into suitablelengths to form the wrappers 40 comprises a blade 41 that is pivotallymounted adjacent to one end as shown at 42 with its cutting edge adaptedto be moved down into engagement with or past a plate or support 43 inthe usual manner.

The plate 43 is mounted upon a base or support 44 that is mounted orformed-upon the upper ends of two rocker arms 45 which are pivoted attheir lower ends upon the frame 1 as shown at 46. A shield or cover 47is secured at its ends to the plate 43 with its intermediate portion ata suitable distance above the plate to form a guide and permit of thepassage of the paper from the rolls 35 and 36 to and beyond the knife'blade or cutter. The cutting mechanism is preferably provided withanother guide which also forms a clamp and is preferably formed byplates or bars 48 and 49 which are yieldingly held together in anysuitable manner, as by means of the bow springs 50, one at each end.This additional guide and clamp is connected with the rocker arms in anysuitable manner, as by means of two arms or projections 51 which extendfrom. the base or support 44 a suitable distance.

The clamp is normally closed so as to engage with the end of the paperand hold it taut when the knife is being depressed to cut the paper sothat if the knife should fail to cut it, as from being dull, the paperwill be torn off so as to form a wrapper. A projection 52 extendsupwardly from the upper member of the clamp so as to be engage by theknife when it is raised and thereby open I the clamp by raising ortilting said member with the springs at the ends as pivot points. Thethroat or opening through the guides and clamp is preferably taperedfrom the side adjacent to the rolls 35 and 36, toward the wrappingmechanism, and a stripper is preferably provided for substantiallyengaging with the lower roll 36, and preventing the paper from beingcarried around the roll, as when there is enough dampness to cause it tostick to the roll. This stripper is preferably formed as a separatepiece 43 which can be mounted adjacent to said roll in any desiredmanner.

As the operation or movements of the parts of the machine arecontinuous, or substantially so, it is necessary to move the bladeforward as it is cutting. the paper, which forward movement isaccomplished by means of suitable cam mechanism and a pitman or link 53leading therefrom to one end of the cutting mechanism where it engageswith the outer end of an arm 54, the inner end of said arm being formedupon or bolted to one end of the base 44 as shown in Fig. 2. The cammechanism comprises a bar 55 which is mounted on the shaft 3 so as to berotated thereby and having two .is provided with two shoulders 58 and59,

the shoulder 58 being inclined and the shoulder. 59 .preferabl being inthe form of a roller which is adpistably secured to an arm 60 from thepitman by means of a stub axle 61 and slot 62. The shoulder or roller 59is so located as to be engaged by the cam like ends of the bar 55 whenthe shaft 3 is rotated in the direction of the arrow and will therebymovethe pitman endwise and cause it to swing the cutting mechanismforward until the end of the cam has passed out from under the'roller 59as shown in dotted lines in Fi 4. By the time the bar 55 and pitman 53have been moved into this sition one of the rollers 56 on the bar will ecarried up into position to engage the inclined shoulder 58 and therebyreturn the pitman and cutter mechanism to their normal positions. Justas the roller 56 passes out of engagement with the upper end of theinclined shoulder 58 the end of the bar 55 is in position for engagingwith the roller 59 and will again move the pitman 53 and the cuttingmechanism forward as above described. As the cutting mechanism isreciprocally moved back and forth lengthwise of the machine in thismanner to correspond with the movement of the paper the heel or outerend of the blade 41 is caused to engage with a cam mechanism so as toswing the blade vertically upon its pivot 42. This cam mechanismpreferably comprises a bracket 63 that is mounted upon one of thestandards 34 and is provided with a vertically arranged side or late64:.

A latch 65 is pivotal y mounted upon the side 64 in such position thatit will ride over the outer end or heel of the cutter and thereby permitthe cutter to remain-in its elevated or open position while the cuttingmechanism is being returned preparatory to cutting off another wrapper.But as soon as the forward movement of the cutting mechanism begins theheel of the blade will engage with the latch 65 and be caused to ride upover it as shown by the dotted arrows in Fig. 3 which will cause theinner or cutting end of the blade to descend into engagement with theedge of the plate 43 and thereby cut offenough paper to form a wrapper40 as the cutting mechanism is carried forward. The blade is held in itselevated or inoperative position by the spring 66 and the end of itsheel is preferably provided with an anti-friction roller 67 After thepaper has been cut into wrappers in this manner it is delivered to acarrier which preferably comprises two airs of endless bands 68 and 69that are a a ted to be actuated by sets of grooved whee s 7 O mountedres ectively upon pairs of shafts 71, one of sai shafts being drivenfrom a sprocket wheel 5 by a sprocket chain 72 and sprocket wheel 73 atone end and the two shafts being provided with intermeshing gearing 7 4at the other end. The wheels upon one of the shafts 71 are shown in Fig.1.

mounted at a greater distance apart than the other wheels upon the othershaft so that the faces or operative ortions of the respective belts 68and 69 will not be in the same plane but will overlap or extend ast eachother as shown in Fig. 9 and will thereby clamp the ed es of thewrappers 40 between them and ho d the wrappers taut and smooth.

The movements of the mechanism so far described are timed tocause awrapper 40 to be de osited upon each succeeding receptacle 7 ust beforethe latter reaches the gate of the supply chute so that as thereceptacle asses nder said gate an oran e Wlll. be ropped upon thewrapper w ich will slig tly fol the wrapper into the cup with its edgesrojecting substantially horizontally and t e orange and wrapper willthen be carried forwar to the wrappin mechanism at which place theoperation of folding the wrapper around the oran e and crimping itsedges together will e completed. But the grippage between the bands isnot suflicient to tear the paper before it is cut off from the roll toform a wrapper.

The folding and wrapping mechanism comprises 0 positely locatedreciprocally mounted bla es or folders 7 5. These folders have theirinner ends formed as diverging fingers 76, shown more particularly inFig. 5, which are of such size that when they are opened to theirfullest extent with their tips just overlapping the orange and itswrapper can be passed down. through the o ening formed thereby. Thereare preferab y-two pairs of these folders suitably spaced apart by meansof plates or blades 77, as to permit of the fingers interlocking, andthe are preferabl slightly curved transverse y as shown in Fig. 1, andlongitudinall as shown in Fig. 6, and are sufliciently rigid to causethem to substantially retain th1s curvature as they are moved back andforth to compress the edges of the paper at the top of the orange.

The folders are adjustable by means of slots 78 and bolts 79, two ofsaid bolts each engaging with the outer ends of the folders to preventpossible outward movement.

The folders are carried upon the outer ends of arms 80 which arepivotally mounted 11 on the spokes of the wheel 4 by means of p1ns 81which extend from the respective spokes to the periphery of the wheel asEach arm is provided near its pivot point with a projection, preferablyin the form of a roller 81, which is adapted to engage with a fixed orstationary cam 82 as the wheel is revolved. The cams 82 are referablyintegral with the bearings 83 of t e shaft 2 and are so formed that asthe wheel 4 rotates the cams will cause the folders to be closed in overthe orange and thereby crimp the edges of the paper together and hold ita suflicient length of time a pivot point are adapted to be seatedbetween pairs of ears 84 upon the sides of the wheel 4 and the basepiece 85 of the presser mechanism is pivotally mounted upon one of theears as shown more particularly in Fig. 5. Secured to the base 85 is ahollow post or stem 86 that projects outwardly substantially radially ofthe wheel 4 and is provided at its outer end with a reciprocator frame87 One of the arms of the frame 8 is longer than the other and isprovided with means for engaging with the orange and forcing it downbetween the fingers of the folders 75 before they have been entirelyclosed in. This mechanism preferably consists of a pad 88 of yieldingmaterial mounted upon a base 89 that is adjustably secured to the longerarm of the frame by a screw threaded stem or plunger 90 and a nut 91.

The frame 87 is normally held outward upon the stem 86 by means of aspring 92 that is seated in a hollow of the stem and engages at itsouter end with a pin 93 that extends through the frame 87 and pro'ectsthrough slots 94 formed in the sides the stem. The frame is providedwith a roller 95 which is adapted to be moved into engagement with apresser arm 96 as the wheel 4 is rotated. The arm 96 is secured to theupper end of a standard 97 that projects upwardly from the frame 1 andis preferably made pivotally adjustable by means of a slot 98 and bolt99. The upper end of the standard 97 is preferably provided with a hooklike extension 100 that is shouldered as shown at 101 so as to occupythe same plane with the arm 96 so as to be engaged by the roller 95after theroller passes down under'the lower end of the arm 96 and isforced outward by the spring 92. In this manner the frame is preventedfrom being driven outward with such force and rapidity as to damage theparts of themachine or prevent their properly perfornnng theirfunctions.

The outer ends of the stem 86 and the frame 87 are adapted to be movedback and forth as shown by dotted lines in Fig. 6 by a cam 102, a roller103 that is mounted on the base 85 and a spring 107 that normally holdsthe roller in engagement with the cam.

The cams 82 are so formed, see Fig. 14, that-as the rollers 81 pass froma to Z) the folders will be partly closed so as to cause the wrapper tobe folded up around the orange as it is forced down between the fingers76, by the plunger or frame 87, then as they pass from b to c thefolders will be held stationary while the fruit is being forced downbetween the folders, then as they pass from c to Z the folders will benearly closed, sufiicient room only bein left for t e resser or plun erthat force the orange own to be with rawn, then as they pass from' d toe thefolders will be held stationary while the plunger is being withdrawn, t en as they pass from 0 to f the folders will beclosed entirely,and held so while the cams pass from f to g to permit the paper tobecome set in its crimped condition, then as they pass from g to hthefolders are quickly separated or opened so as to permit the orange to beejected by the expansion of the s ring which has been compressed by theescent of the frame 87.

Located upon the inner face of each of the arms 80 is a spring finger103 preferably formed from a flexible strip of metal having its upperend adapted to be forced into engagement with the wrapper when the armsare moved inward to close the folders as shown in Figs. 7 and 8, andthereby assist in the operation of wrapping the orange. The lower end ofeach finger is folded upon itself substantially V-shaped, as shown at104, with the inner end of the folded portions of the two springsadapted to be forced into engagement with the stem 13 after the stem hasbeen depressed or forced into a spoke of the wheel 4, to its fullestextent, the spokes of the wheel being made hollow for that purpose, asshown in Figs. 7 and 8, and thereby hold the stem by frictional contactagainst outward movement. A screw 105 is passed through the foldedportion of each finger into the base of the arm 80 so as to hold the finer in position and adjust the tension of sald end with the stem 13, andthe other or longer arm of the V is adapted to fit within recesses 103on the sides of the plates 16 of the chain 6.

In using a machine as above described a roll of paper is mounted at theforward end of the machine and a supply of oranges is fed through thesupply spout and power from any'suitable source is applied through thebeltwheel 10. As the parts revolve the paper is fed forward and cut intosuitable lengths to form wrappers for the oranges and one wrapper isplaced upon each orange receptacle as said receptacles move forward. Asthe receptacles pass under the supply mechanism each one is providedwith an orange which is carried forward until it stands directly underthe pad 88 of the plunger or presser frame 87, which pad and frame arethen caused to descend by the engagement of the roller 95 with the.upper end of the arm 96, the folders having been partly closed by therollers 81 passing from a to b on the cams 82 as heretofore described.As the receptacle and orange continue their forward movement the frame87 is also carried forward and gradually forced downward by the theparts occupy this position the arms. 80

the inner ends 106 o the sprin are gradually forced inward by therollers 81 passing from c to d on the cams 82, until the fingers arenearl closed at which time will engage with the stem 13 with sufiicientpressure to hold ltagainst return movement and thereby permit of thewithdrawal of the pad 88 by the return movement of the frame 87/justbefore the complete or final closing of. the folders. The orange is thencarried forward with the folders in their closed position so as to causethe paper to become set so as to retain its crimped or folded positionaround the orange after which the roll ers 81 pass fromg. to h oftheearns 82 and thereby quickly open the folders and permit the spring 15to e ect the orange into a suitable box or receptacle. Prior to theoutward movement of the stem 13 and receptacle 7 to eject the orange inthis manner the spring 107 that holds the roller 103 in engagement withthe cam. 102 causes the upper end of the stem 86 and the frame 87 to beswung back as shown. by dotted lines in Fig. 6 out of the path of theejected orange. As the wheel: continues to revolve the stem 86 and frame87 are held in this withdrawn position so that they can pass upwardly asshown in Fig. 1 Without engaging with the sprocket 6 and plate 16. Butjust before the frame reaches the position-in which the pad 88 is to bepressed down onto the orange as above described the cam 102 by itsengagement with the roller 103 forces the stem back into its originalposition with the roller 95 in position for being engaged by the arm 96.

By means of the adjusting mechanism the machinecan be readily adaptedfor oranges of different sizes and although I have described the machineas bemg especially adapted for use in wrapping oranges it is evidentthat it can be readily used for wrapping many other kinds of fruit orobjects by properly adjusting the same.

By providing the printing mechanism each wrapper can be provided withany suitable advertising or other designating matter and the fruits canbe quickly and successfully wrapped or inclosed in a neat and attractivemanner. After the fruit has been discharged from the machine it can bepacked in boxesin the usual manner and thereby properly prepared formarket.
